The embodiment of the application provides a water supply device, as shown in fig. 1 and 2, the water supply device includes: the water channel flow direction switching device 1 and the water storage device 2, wherein the water channel flow direction switching device 1 is provided with a water flow inlet 12, a first water flow outlet 13 and a second water flow outlet 14 which are used for communicating with the hot water supply pipeline 3, and the water channel flow direction switching device 1 controls one of the first water flow outlet 13 and the second water flow outlet 14 to be conducted based on the temperature of the water flow led in by the water flow inlet 12, wherein the temperature of the water flow when the first water flow outlet 13 is conducted is higher than the temperature of the water flow when the second water flow outlet 14 is conducted; the water storage device 2 is connected to the second water outflow opening 14 for storing water guided out of the second water outflow opening 14.

It can be understood that when the water flow temperature of the hot water supply pipeline 3 is low, the water flow with low temperature can be guided to the water storage device 2 for storage through the second water outlet 14 based on the waterway flow direction switching device 1, so that water with low water temperature in the hot water supply pipeline 3 can be stored in the process of using hot water, and the waste of water resources is effectively avoided.

Illustratively, the hot water supply line 3 may be a supply line for domestic hot water, for example a supply line for shower hot water or a supply line for kitchen hot water, which may meet the hot water demand of the domestic life. The water supply device of this application embodiment can effectively reduce the hot water use in-process of family life, because the cold water needs to be discharged the waste of water resource that leads to in the hot water supply line.

For example, the first water outlet 13 is connected to the shower head of the shower enclosure, so that the user can store the original cold water in the hot water supply pipeline 3 into the water storage device 2 through the second water outlet 14 during bathing, thereby reducing the waste of water resources, and particularly for the case that the hot water supply pipeline 3 between the shower enclosure and the water heater is longer, the waste of water resources can be greatly reduced.

Illustratively, the waterway flow direction switching device 1 includes: the valve rod 15, the connecting piece 16 and the temperature sensing assembly 17 are arranged in the shell 11. The housing 11 is provided with a water inlet 12, a first water outlet 13 and a second water outlet 14. The valve stem 15 has a first plug that mates with the first water outflow opening 13 and a second plug that mates with the second water outflow opening 14. The first plug and the second plug may be in a ball-shaped or cone-shaped state, and the first water outlet 13 and the second water outlet 14 form a mating surface that mates with the corresponding first plug and second plug, so that those skilled in the art may reasonably design the plug according to the needs, which is not limited in the embodiment of the present application. One end of the connecting piece 16 is connected to the valve rod 15, the other end of the connecting piece 16 is connected to the temperature sensing assembly 17, and the temperature sensing assembly 17 drives the connecting piece 16 to move based on the temperature of water flow, so that the valve rod 15 is driven to conduct the first water flow outlet 13 or the second water flow outlet 14.

As shown in fig. 1 and 2, the first water outflow port 13 and the second water outflow port 14 are horizontally disposed opposite to each other, and the housing 11 is provided therein with a first support member 18 for supporting the valve rod 15, for example, the first support member 18 may be provided with a through hole through which the valve rod 15 is provided, the valve rod 15 may be displaced in the horizontal direction, and the valve rod 15 has a first state in which the first water outflow port 13 is turned on and the second water outflow port 14 is turned off, and a second state in which the first water outflow port 13 is turned off and the second water outflow port 14 is turned on.

Illustratively, the connector 16 is a spring that is hingedly connected to the valve stem 15. As shown in fig. 1 and 2, the connecting member 16 is preferably a compression spring, and the compression spring is under the action of the temperature sensing assembly 17, when the temperature of the water flow is low, the driving valve rod 15 is in the second state, and when the temperature of the water flow is high, the driving valve rod 15 is in the first state.

Specifically, when cold water flows into the water inlet 12, the temperature sensing assembly 17 is in a contracted state, and the valve rod 15 is pushed by the pressure spring to close the first water outlet 13 rightward, and simultaneously opens the second water outlet 14, and at this time, the cold water flows into the water storage device 2 through the second water outlet 14, and the cold water is stored in the water storage device 2 for use. When the water flowing into the water inlet 12 becomes hot water and the temperature reaches the action temperature of the temperature sensing assembly 17, the temperature sensing assembly 17 drives the compression spring to shift rightwards at the end connected with the compression spring, and when the compression spring shifts rightwards and exceeds the hinging point of the compression spring and the valve rod 15, the valve rod 15 is rapidly switched to a first state under the pushing of the compression spring, namely, the first water outflow opening 13 is conducted and the second water outflow opening 14 is cut off. It will be appreciated that when the connecting member 16 is a compression spring, a rapid switching of the valve stem 15 between the first and second states can be achieved without causing false movements due to reciprocating displacement of the valve stem due to momentary fluctuations in water temperature.

In some embodiments, the temperature sensing assembly 17 comprises: the support rod 171, the temperature sensing element 172 and the moving member 173 are arranged on the support rod 171, the temperature sensing element 172 and the moving member 173 fixed on the temperature sensing element 172 are arranged on the support rod 171, and the moving member 173 is connected with the connecting piece 16 and is used for driving the connecting piece 16 to move under the deformation of the temperature sensing element 172.

The temperature sensing element 172 may be, for example, a deformable member made of a thermally sensitive material. For example, the temperature sensing element 172 may be formed of a material having an outer shape and size sensitive to temperature, such as a bimetal assembly or an air bag. The bi-metallic strip assembly is a composite material composed of two or more metals or other materials having suitable properties. The bimetal is also called a thermal bimetal, and because of the different thermal expansion coefficients of the component layers, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetal is bent towards one side of the passive layer, and the curvature of the composite material changes to generate deformation.

The structural form of the temperature sensing element 172 is not particularly limited in the embodiment of the present application, as long as it can be deformed by temperature sensing.

In some embodiments, the temperature sensing assembly 17 further comprises: and a return spring 174 sleeved on the support rod 171, wherein the return spring 174 is used for driving the moving member 173 to return.

As shown in fig. 1 and 2, the housing 11 is provided with a second support 19 for supporting the temperature sensing assembly 17, for example, two second supports 19 on the left and right in fig. 1 and 2, and it is understood that the support rod 171 may be horizontally displaced along the second supports 19. The temperature sensing element 172 may be sleeved on the support rod 171 and abuts against one side of the second support member 19, the moving member 173 follows the displacement of the temperature sensing element 172 and is fixedly connected with the support rod 171, and the return spring 174 is sleeved on the support rod 171 and abuts against the other side of the second support member 19. As shown in fig. 2, when the temperature sensing element 172 expands and deforms when the temperature rises, the moving member 173 is driven to displace rightward, and the supporting rod 171 is driven to displace rightward, so that the return spring 174 is in a compressed state, and the moving member 173 displaces rightward to a set position, so that the connecting member 16 drives the valve rod 15 to switch to the first state. It will be appreciated that when the temperature of the water flow in the housing 11 is low, i.e. the temperature sensing element 172 returns to the pre-deformation state, the return spring 174 may drive the support rod 171 to displace to the left, so that the moving member 173 drives the connecting member 16 to return, thereby switching the valve rod 15 to the second state, and the return spring 174 may improve the reliability of the state switching of the valve rod 15.

In some embodiments, the water storage device 2 comprises: the water storage container 21, the water storage container 21 is provided with a water inlet hole 22, a water outlet hole 23 and a vent hole 24, and the water inlet hole 22 is connected with the second water outflow hole 14; the water supply device further includes: the water return line 4 connects the water outlet hole 23 and the first water outlet 13.

Here, the water storage container 21 may be a water storage bag or a water storage tank, which is not limited in the embodiment of the present application.

It can be appreciated that, for the convenience of space arrangement, the volume of the water storage container 21 is limited, in this embodiment, the water outlet hole 23 of the water storage container 21 is communicated with the first water outlet 13 through the water return pipeline 4, so that when the valve rod 15 is in the first state, hot water in the hot water supply pipeline 3 can flow out through the first water outlet 13, and under the negative pressure of hot water flowing rapidly in the channel of the first water outlet 13, cold water stored in the water storage container 21 can be mixed with hot water in the channel through the water return pipeline 4 and then discharged, and the water after cold and hot mixing flows out by the water supply device (such as a shower head) connected with the first water outlet 13, so that the cold water stored in the water storage device 2 is utilized and cannot be wasted. Thus, the cold water in the hot water supply pipeline 3 can be utilized in the use process of showering and the like, the volume of the water storage container 21 can be reduced, and the practicality is high.

Illustratively, a shut-off valve 25 for shutting off the second water outflow opening 14 when the internal water level is lower than the set water level and/or a check valve 41 for unidirectional conduction in the direction from the water outlet hole 23 to the first water outflow opening 13 are provided in the water storage container 21.

As shown in fig. 1 and 2, the stop valve 25 may be a float switch, and a check valve 41 is disposed on the water return line 4. The check valve 41 can effectively prevent the water of the first water outflow opening 13 from flowing backward into the water storage container 21. When the water in the water storage container 21 is set above the water level, the water in the water storage container 21 can be guided out to the channel of the first water outlet 13 to be mixed with the hot water under the action of negative pressure through the loop pipeline when the first water outlet 13 is conducted. Preferably, the flow of the check valve 41 can be adjusted, and the mixing temperature of the hot and cold water can be further controlled by adjusting the water outlet size of the check valve 41, so that the user experience is improved. When the water in the water storage container 21 is lower than the set water level, the float switch closes the water outlet hole 23.

In some embodiments, the water supply device further comprises: the cold water supply line 5 is connected to the first water outflow opening 13.

It will be appreciated that when the float switch closes the outlet aperture 23 of the water reservoir 21, cold water can be supplied to the passage of the first water outlet 13 via the cold water supply line 5, thereby achieving a cold-hot water mixing effect. Alternatively, a regulating valve for regulating the flow rate of the external cold water source may be provided on the cold water supply line 5, thereby facilitating the user to regulate the effect of cold water-heat mixing.

The embodiment of the application also provides a water supply system, which comprises the water supply device and the water heater, wherein hot water of the water heater is communicated with a water inlet 12 of the water supply device through a hot water supply pipeline 3.

It is understood that the water heater may be an electric water heater, a gas water heater, a solar water heater, or the like, which is not limited in the embodiment of the present application.

It should be noted that, based on the water supply device described above, the water supply system can effectively save waste of water resources.

It should be noted that: the technical solutions described in the embodiments of the present application may be arbitrarily combined without any conflict.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application.
